 Differentiate between metals and non-metals on the basis of chemical properties ?. 

Answer:

Property	; Metals	Non-metals |
1. With oxygen, (nature of oxides)	Metals form basic oxides some of which form alkalis when dissolved in water.	Non-metals form acidic or neutral oxides.
2. Displacement of hydrogen	Metals displace hydrogen from acids.	Non-metals do not displace hydrogen from acids.
3. With chlorine	Metals form chlorides which are ionic compounds.	Non-metals form chlorides or chloro compounds which5 covalent in nature.
4. With hydrogen	Few metals form hydrides which are ionic (electrovalent) in nature.	Non-metals form stable covalent hydrides.
5. Chemical nature	Metals are reducing agents.	Non-metals are oxidizing agents except carbon and hydrogen. Carbon and hydrogen are good reducing agents.
